SPECJZFICA'VTION forming part of Letters Patent No. 609,557, dated August 23, 1898.

' Application nea september so, 1396. serial No. 607,406. ou modem To all whom it may concern:

Be it knownthatl, `WILLIAM H. PHELPs, a citizen of theUnited States, residing at Fort Wayne, in the county of Allen, in the State of Indiana, have invented certain new and useful `Improvements in Vaporizers for I-IydrocarbonOils; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will en- 'able others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to improved means for vaporizing hydrocarbon oils or similar fluids.

The object of my invention is to provide a vaporizing apparatus for petroleum-engines having an improved means for preventing the unvaporized liquid from passing into the engine through the vaporizing-chamber, having improved means for supplying oil to the vaporizing-chamber, in conjunction with an improved valve for admitting air to said chamber by which the vaporization is effected, having an improved means for regulating the fuel-supply to' saidchainber, having a sight-feed to'as'sist in regulating the fuelsupply, and having an improved means for feeding oil by hand tostart the engine.

My improved vaporizer comprises a globular metallic body having proper screw-threaded openings for the oil-conduit, the air-induction port, and for the vapor-eduction. port,"

respectively, an improved air-valve having a striker-plate adapted for an automatic fuelfeed, an obliqueshield interposed between the vapor-eduction port and the fuel and air openings to prevent the escape of any unvaporized liquid into saidvapor-port, a cone feed-valve for the fuel-supply, and means for regulating the operation thereof.

In the accompanying drawings similar reference-numerals indicate like parts throughout the several views, in which- Figure 1 is a longitudinal vertical central section of my improved vaporizer, showing the. relative arrangement and manner of connecting the operative parts thereof. Fig. 2

is a view in elevation of my improvement,

taken at right angles .to Fig. 1, showing the general contour and also showing the means for operating the air-valve and the fuel-supply valve by hand` in starting the engine. Fig. 3 is a detail of the sight-feed. Fig. 4L is a detail of the hinged air-valve, showing its connection with the striker-plate for operating the fuel-feed. l Fig. 5 is a detail of the valve governing the fuel-supply. Fig. 6 is a bottomzplan of` the upper portion of the feed-valve in transverse'section, taken on the line A A` of Fig. 5, showing the peripheral recesses in the stem thereof.

` All parts of my invention are made of suitable metal.

The vaporizer body or shell 1 may be of any proper form or dimensions,` though it is preferably' globular in form, as shown, its hollow interior forming a vaporiZing-chamber having the diametri@ screwthreaded openings'Z and 3 for the induction air-conduit and the vapor-outlet pipe, respectively, and is provided upon its top side thereof Witha screw-threaded opening into which is tightly fitted by a screw-threadedV connection a hollow cap 1 2, having a central opening in the top thereof. In the opening in said cap is secured by a screw-threaded connection the lower end of the sight-feed 13, which is elongated, as shown, open at the top, and hasa suitable glass tube vertically arranged in its upper hollow portion, as seen in Fig. 1. The lower end of the said feed 13 is provided with a central vertical aperture for the feedvalve 2l, the upper portion of said aperture having converging sides to form a seat for the said conical feed-valve 2l. The upper chambered portion of said feed 13 has two diametri@ sight-openings of-common arrangement, Fig. 3, through which the operator can see the adjacent ends of the said feedvalve and the adjustable screw-threaded plug 16 for limiting the vertical play of said valve, whereby he can regulate at pleasure the distance between the said ends. The said feedvalve 21, of conical form and adapted to iit a conical seat, as described, is provided upon its lower end with a cylindrical extension 23.,

provided with a plurality of longitudinal peripheral recesses 24., Fig. 5, adapted to conduct the .fuel-oil after each operation of the feed-valve'to the convex upper surface of the striker-plate, after which it is evaporated by IOO the inlet air-current in the manner hereinafter described. The said valve also has an upward reduced extension 22, adapted to strike the lower end of the said plug 16 at each operation thereof, thereby limiting the opening movement of said valve, and thus regulating the quantity ofy liquid adlnitted at each upwith an lapertured head 8, to the outer face of which is detachably fixed the disk-valve by means of a proper holding-screw 9 or in any other suitable manner. The said valve 5 1s preferably concavo-conveX, as shown, having an annular face adapted to normally rest upon a proper coincident seat on the extended inner end of said opening 2. The strikerplate 10, preferably in the form of a planoconveX disk, is integral with the said hinge 6, being united thereto by the short neck 29, Fig. 4, and is provided upon its upper conveX face, preferably in the center thereof, with an integral vertical lug 11, arranged in vertical alinement with the stem 23 of said valve 21 and adapted to engage and open said ,valve at each opening movement of the said air-valve 5. Arising from the bottom of said vaporizing-chamber on a line between the said openings 2 and 3 and cast integral with the said body 1 is arranged the oblique transverse liquid-shield 4, preferably semielliptical in form and adapted to guard the said vapor-exit opening 3 againstthe admission of any unvaporized liquid 30, which will be received and retained by said shield in that compartment of said vaporizing-chamber containing the said air-valve, as seen in Fig. 1. In the open upper end of the said sight-feed casting 13 is detachably secured by a screw-threaded connection the lower end of the hollow casting 14, having both ends thereof vertically apertured to admit the said adj ustin g-plu g 16. The opening in the lower end thereof is of a somewhat greater diameter than that of the said plug to provide a constricted annular passage for the fuel-oil. In the casting 13 is loosely mounted the opentopped glass receptacle 20, forming an auxiliary reservoir into which the feed-valve opens. The said casting 14 has in its central globular portion a small reservoir-chamber for fuel-oil and has a laterally-extended screw-threaded opening to receive the outer end of the fuelsupply pipe from the oil-tank, Upon the eX- fa,- ternally-screw-threaded end of said casting 14 is secured a proper stuffing-box 18, in which the said plug 16 is rotatably mounted.

The said plug 16 has iiXed upon its upper end a circular head 17, having a series of peripheral notches adapted to engage the upper free end of the spring 19, having its lower end fixed in any, proper manner in the upper portion of said casting 14 and adapted to secure said plug in any desired adjustment.

The operation of my invention thus described is, briefly stated, as follows: As the inlet air-valve 5 is pivotally hinged in the vaporizer body or shell 1, it will be automatically lifted from its seat by the inrushing aircurrent at each stroke of the engine, thereby simultaneously elevating the strikerplate 10 with sufficient force to open the said feed-valve 21 by lifting it vertically from its conical seat to the limit of its movement, which is determined by the distance at which the lower end of the said adjusting-plug is set from the upper extended end of said feedvalve, thereby admitting the oil from said sight-feed in sufiicient quantity at each opening movement of the feed-valve to make one charge for the engine. The oil thus admitted is conducted downwardly into the vaporizingchamber by the said peripheral recesses 24, from whence it drips onto the upper convex surface of the said striker-plate, producing a spray, which is then evaporated by the said air current and then passes outwardly through the vapor-conduit 3 to the explosionchamber. Should any of such fuel-oil thus admitted to the vaporizer chamber remain unvaporized, it will settle and be retained in that portion of said chamber between the transverse shield 4 and the said air-valve and will thus be prevented from being carried into the vapor-conduit by the said shield. It will be seen that the said air-valve and striker plate can be inserted or removed through the opening which is closed by the removable cap 12. It is obvious that by means of thesaid sight-feed and the said adjusting-plug 16 the operator can readily regulate the supply of fuel -oil admitted at each operation of the feed-valve by limiting at pleasure the upward movement of said valve. It is also obvious that in starting the engine the fuel-oil can readily be admitted to the vaporiZing-chamber and supplied to the explosion-chamber in the usual manner by operating the air-valve and striker-plate by means of the thumb-screw head 25, Fig. 2.

It is obvious that my feed-valve can be as readily regulated when in operation as when at rest.

- Having thus described my invention and the manner of operating the same, what I desire to secure by Letters Patent is- In a vaporizer for hydrocarbons, a shell having an inlet-passage upon one side, an outlet-passage upon the other, and a shield placed in between the two passages; a hinge provided with a valve for closing the inletopening upon one arm and a striker-plate upon the other, combined with a screw-plug which is inserted into the top of the shell, a Signed by me at Fort Wayne, FState of In- Vei'ticaily-moving Valve which is operated by diana, this 22d day of September, A. D. 1896. the striker-plate, a suitable shell or casing through which the Valve is placed and through which the supply of oil is fed, and means for regula-ting the upward movement of the valve, y substantially :is shown and described.
